Shoe Shank Stiffness Tester
Category：Footwear Strength Tester
Introduction
Standard：
SATRA TM256: Flexural and torsional stiffness testing for athletic, safety, and casual footwear.
SATRA TM194: Dynamic fatigue resistance evaluation for shoe midsole and outsole integrity.
Product Advantages：
1. Dual-Mode Testing
Longitudinal & Torsional Stiffness: Simultaneously measures bending resistance (flex) and twist rigidity in a single cycle.
Universal Compatibility: Adapts to all shoe types—running, hiking, work, and orthopedic footwear.
2. High-Speed Automation
30 Cycles/Minute: Industrial-grade motor for rapid fatigue testing (0–50° flex angle).
Zero-Drift Actuators: Maintains ±0.1° angular accuracy over 100.000 cycles.
3. Precision Sensing
Strain Gauge Technology: 0.01 N·m resolution for torque and 0.1° angular feedback.
Self-Compensating Algorithms: Corrects for specimen slippage and hysteresis.
4. User-Centric Workflow
7” Touchscreen HMI: Pre-loaded SATRA protocols with adjustable test parameters.
Real-Time Curve Tracing: Live plots of torque vs. angle during testing.
5. Advanced Data Management
USB/PC Connectivity: Export raw data, cycles-to-failure, and stiffness coefficients.
Cloud Integration: Wireless sync to LIMS platforms for collaborative R&D.
Product Features：
Dynamic Testing System:
Servo-electric actuator with 0–50° programmable flex range.
360° torsion axis with ±180° rotational limits.
Precision Fixturing:
Quick-change shoe clamps for US Men’s 5–15 (EU 38–50) sizes.
Adjustable torsion line alignment for varied shoe geometries.
Sensor Suite:
1.000 N load cell for flexural force measurement.
50 N·m torque sensor with overload protection.
Software Bundle:
ShoeFlex Pro™: Automated stiffness coefficient calculation (ASTM D790 equivalent).
Fatigue Analyzer: Predicts lifespan via stress-cycle (S-N) curve modeling.
Safety Systems:
Emergency stop with E-Stop loop monitoring.
Over-torque shutdown at 110% of rated capacity.
